Abstract

The present invention relates to a battery pack, comprising: a battery pack housing; a battery unit accommodated in the battery pack housing; a printed circuit board (PCB) accommodated in the battery pack housing; and a power tool connection end accommodated in the battery pack housing and disposed on the PCB. The power tool connection end comprises an integral metal sheet electrical terminal, wherein, when the battery pack is mounted on the power tool, the metal sheet electrical terminal is electrically connected to an electrical connector of the power tool, the metal sheet electrical terminal having a terminal lower end, the terminal lower end being directly electrically connected to the PCB. The present invention further relates to a power tool comprising such a battery pack.
